I would disagree. For example phase is one of the parameters of the grain, so to modulate the phase how come it an invention, but to modulate a filter cut off is not? The same tolerance is inherent part of analogue component, as it is very difficult to achieve exact value of e.g. capacitance, so components are manufactured with different levels of tolerance, so if you simply acknowledge this fact of life in your simulation how is that an invention?
